The liquid-free trap for trace level acidic and basic AMC and components thereof in the present invention relies on a solid material to trap acidic or basic AMC in a gas stream, for example, from a cleanroom or a semiconductor manufacturing facility. The liquid-free trap for trace level acidic and basic AMC and components thereof can be used in any suitable orientation, including horizontal and vertical orientations. The liquid-free trap for trace level acidic and basic AMC and components thereof can comprise a housing comprising a hollow, elongate upstream component with tubular portions; a hollow, elongate downstream component with tubular portions; and a locking nut member to secure the upstream component to the downstream component, the upstream component and the downstream component together creating a chamber space that is sealed from the environment and situated in a flow path between the inlet and the outlet. The space created by the upstream and downstream components together can accommodate a rigid sintered hydrophilic material trap member for trapping trace level acidic or basic AMC. 

CLAIM The ornamental design for a liquid-free trap for trace level acidic and basic AMC and components thereof, as shown and described.
